16 GB DDR4-3200 ECC RDIMM for Supermicro EPYC

This registered DIMM adds 16 GB of error-correcting memory to compatible Supermicro H11SSL-C motherboards built for AMD EPYC processors. It runs at DDR4 3200 (PC4-25600) with a CAS latency of CL22 and 1.20 V. The module uses major OEM chips from Samsung, Micron or Hynix and carries a 2Rx8 rank configuration.

Registered ECC with 2Rx8 organisation

The single specification that decides fit is the registered ECC RDIMM format combined with 2Rx8 rank organisation; unbuffered or single-rank modules will not work in the target Supermicro platforms. DDR4 3200 speed and 1.20 V voltage must match the motherboard memory controller settings. No heat spreader is fitted, so airflow across the 288-pin module is required.

Simple slot insertion, verify population rules

Installation is a matter of aligning the notch on the 288-pin edge connector and pressing firmly until the retention clips latch. The common error is mixing registered and unbuffered DIMMs or exceeding the per-channel rank limit defined in the Supermicro manual. Always confirm the supported population sequence before adding this module.

Questions about this item

What does the DDR4 3200 speed rating deliver in a Supermicro H11SSL-C system?

It runs at 3200 MT/s on the EPYC platform, providing PC4-25600 bandwidth with CL22 latency for registered ECC workloads.

How does the registered ECC RDIMM interface affect usable capacity and stability?

The 2Rx8 registered design adds a clock cycle for buffering, enabling reliable 16 GB operation with full error correction on supported Supermicro boards.

What physical slot and clearance does the 288-pin module require?

It fits a standard 288-pin DDR4 RDIMM slot; the module has no heat spreader, so it clears tight server DIMM spacing without extra height.
